Well I found this exploit when the previous swimming in the air exploit was nerfed. This is a new way to swim in the air....but i've been notified that this has been fixed in 2.2 so use it as much as u can before it is nerfed again. I am only releasing this cuz blizz seems to have found out about this. Otherwise I would still only reply to PMs.
-Duel a priest
-mount and fly up a bit
-have the priest start casting MC
-As SOON as the MC hits dismount (I count down from 3 after he starts casting it mods might help)
-After u get rid of the flight buff spam jump and have priest spam jump too for good measure.
It takes a few tries to get it right but it is very specific so be patient. Also I've heard it has varying difficulty for different races.
Notes:
-You can't loot any mobs u kill in the air. To loot kill the mob on the ground b4 it dies
-Druid flight form doesn't seem to work.
-You can go to exodar/silvermoon like this
-You can mount ur ground mount but dont mount you're flying mount
-You cant regularly do this in Azeroth
Happy Exploiting while it lasts
Side note: Is it just me or are the exploiting forum really dull lately with at best a relatively good find a GM post?
